Darren thanks for the reply, its cool to get one direct on a forum. I'm tempted to go with the rc4 I might take my buddies off him. I take it you can beef up the mid stroke a little more for the VPP type suspension.
I'm really interested in learning how its done do you have a link to the process I couldn't find it on your site. I really liked my push tune I had before, I didn't know what was going on but it felt good!
